A TTORNEYUSZ Application filed August 5,

To all whom it may concern:

Be it lrncwn that l, HERMAN C. Doreen, a citizen of the United States, and resident of Ushlrosh, in the county of Winnebago and State of l Jisconsin, have invented new and useful Improvements in Washing Machines, of which the following is a description, refrence being had to the accompanying drawngs, which are apart of this specification.

present invention relates to certain new nd useful improvements in washing machines of that type used in washing weara A a el and the like.

the washing machines now in common everyday use, a reciprocating and oscillating dolly is employed which has proven very unsatisfactory in that it is practically impossible to use the same in connection with fine materials as the dolly often tears the clothing,

Hence with these inherent objections in mincl my invention has for one oi its ob jects to provide a washing machine in which a plurality of spray nozzles are employeci, so arranged as to clirect a spray of fiuicl therefrom in a direction to impart the clothes within the washer a whirling movement.

Another object of the present invention is to provide a washing machine of the class clescriheci employing a plurality of spray nozzles so arranged as to impart a whirling movement to the clothes being cleaned; in which the spray from the nozzles will he of sufficient strength to loosen the dirt from the clothes,

A further object of this invention is to provide means for selectively supplying fluid to a plurality of spray nozzles so arranged as to import it whirling movement to he clothes being cleaned.

-A still object oi? this invention is to provide means for circulating the wcte in the machine through the cleans ing spray nozzles.

A still further object of the present on is to provide it cylinder having a re "1Pl'-i) sting piston therein arranged oraw c roni the washing machine coni rec the same through one of e rality of spray nozzles arrange-cl to dise within the container of he washing chino ancl means operable upon one coninioveznent of the reciprocating piston conn ct the port of the cylinmen spray nozzle of the plural- Specification of Letters Patent.

1919, enial of the principies ti erect, and n which: Figure l is a view part in section and in elevation of a washing machine embed ing the several f atures of any invention. Figure 2 1s a top plan of tne'wasn mg machine container, sold container being shown with the usual. cover removeoi there vfi irons.

Figure 3 is detailed sections.

ure 1.

Figure i is elevational view of plying cylinder, piston reciprccati and rotary valve operating means, being taken look ng at the sicle of der to the right 1th reference and Figure 5 is s top plan view oi ing mechanism for the reciproc and selectively rot liable valve ing taken on the line 5 Referring now moi accompanying draw designates the work con '7 the supporting legs and 8 a transverse p we ceiving the plying water to the a i er pressure to the adjacent in Figure 2 in. 1 nectecl by counter-bored end 13 of a cylinder 14 adapted to be secured centrally to the underside of the bottom wall 9.

Mounted in the counter-bored end 13 is a substantially inverted cup-shaped rotary valve 15 carried by .a valve rod or stem 16, journalled at its lower end in the bearing 17 fixed to the base 8. The valve 15 has a single port 18 in its side peripheral wall adapted to be selectively registered with the ends 19 of the pipes 12 communicating with the counter-bored end 13. The valve 15 is rotated to selectively register with said ends 19 by means to be later described.

Reciprocally mounted within the cylinder 14 is a piston 20, having its rod 21 centrally bored and slidably mounted on the valve stem or rod 16, and having its lower end slidably mounted in a packing gland 22, formed centrally on a cap 23, closing the lower end of the cylinder. The lower end of the cylinder is in communication with the container or receptacle 6 by means of a circulating pipe 24 leading from the bottom of the container, as at 25, and connected with the cylinder, as at 26, the end 25 of the pipe being covered by a screening member 27.

The piston 22 is reciprocated, by means to be later described, and in its downward movement a plurality of gravity controlled valves 28 carried thereb are operated to allow the water supplie to its underside by the circulating pipe 24 to pass therethrough, and in its upward movement the valves 28 automatically close and the water then on the up er side of the piston is forced through t e ort 18 of valve 15 and out through the disc arge jet 11 of the spray nozzle, having its end 19 registered with the port 18. The piston in its upper movement creates a suction or vacuum on its under side and draws water into the cylinder through circulating pipe 24, in order that in its downward movement there will be water to pass by the valves 28 as before described.

The iston 20 is r'eciprocated by means of an e ectrical motor 29 in geared connection with a gear 30 carried by a shaft 31, journalled in bearing 32 and having a crank 33 formed thereon and connected with a lever 34 having one end pivoted, as at 35 to a brace 36 carried by a rear wall of the container 6, by means of a link 37. The other end of the lever 34 is forked to provide a bearing of spaced arms 37 pivotally connected to a cross head or bar 38 carried by the lower end of the piston rod 21. Thus it will be obvious that. by the rotation of the crank 33 through the medium of the motor 29, the piston 20 will be reciprocated within the cylinder 14.

The valve 15 is rotated one step upon each working stroke of the piston 20 so that first one spray nozzle will be coupled with the port 18 upon one upward strokeof the piston, and another upon the next upward stroke of the piston as will be apparent. The means I employ for intermittently rotating the valve 15 one step at a time comprises a ratchet wheel 39 fixed to the valve stem 16 near its lower end and selectively en ageable with its teeth 40 is a pivoted'paw or dog 41 carried by a lever 42, having one end freely pivoted on the rod or stem 16 adjacent the ratchet wheel 39, the pawl or dog 41 being normally urged to engage the periphery of the wheel 39 by means of a flat spring 43. The other free end of the lever 42 is pivotally connected with the long arm 44 of a bell crank lever by means of a link 45, having a pivotally connection with the arm 42 and a universal joint connection, as at 46, with the bell crank lever. The bell crank lever is pivoted to a standard 47 carried on the base 8 and has its other shorter arm 48 connected to the lever 34 medially of its ends by means of a pivoted link 49.

The bell crank lever 48 is so proportioned and connected with the lever 34'so that when the iston 20 is on its upward movement, the 0g or pawl 41 will be moved in an anticlockwise direction with respect to Figure 5 to en age the pawl behind the next tooth 40, as eplcted in dotted lines, so that upon its downward movement the pawl 41 will rotate the ratchet wheel one tooth in a clockwise direction to position or register the port 18 with the end 19 of the next spray nozzle.

In order to prevent the valve 15 from being rotated in anti-clockwise direction when the pawl'41 is riding over the next tooth, by the friction thereagainst the ratchet wheel caused by its spring 43, I provide a plurality of notches on recesses 50 in the side wal of the valve 15 so arranged that when the port 18 is registering with the end 19 of any one pipe 12, one of the notches will be engaged by a spring operated ball or check 51 carried by the adjacent portion of the counter-bored end 13, as at 52, see Figure 3.

- The check or ball 51 prevents the accidental movement of the port 18 from registering with its adjacent pipe end 19.

As best shown in Figures 1 and 2, the sharp corners of the container 6 are relieved by inclining them, as at 6, so that no resistance will be offered to the clothes in their whirling movement. The jets 11 are so arranged that the sprays 11 ejected therefrom will be upwardly at an angle from the bottom 6 and towards the adjacent spray nozzle 10 whereby a whirling movement will be imparted to theclothes within the container 6 by the sprays 11. The sprays 11' take the place of the reciprocating or oscillating dolly now gen ally emoloyed in washing machines and e spray is oil "force to play upon the c othes penetrating thcrethrough, which gether the whirling movement of the othes thoroughly cleanses the same,

ll claim as my invention is:
